Rust killer

[CLIVE58]

Just bought a 30 years old steel cruiser stern. Calorifier had been leaking which caused a hole in the base plate, this has been welded now and is fine. The rest of hull inside has some rust that im going to get of with a wire brush. I want to know what to treat it with after. There are so many products out there so which one please.

I would always use Vactan, no messy washing away the surplus after application.

For "the rest of the hull inside"?  I also rate Vactan by the way, but for more localised work - this sounds like the entire bilge or perhaps more.

a hole (like seeing daylight) or a crater/depression?  

 

............  yes, Vactan wherever there is rust. 

PS: it is of no value if you brush the metal to shiny bright, it is only effective on rusty surfaces.

Vactan has worked very well in my engine 'ole (the surfaces are not oily, because I have a modern engine).

Vactan does a fine job in our permanently wet gas locker. Gets my vote, and as has been stated, no messy rinsing.

Another vote for Vactan. I’m never without it.

I've never seen the Pope but I've been to the Yucatan.

I am a big Vactan advocate myself, but he'll have to be quite well heeled to buy Vactan in sufficient quantities to coat the whole of his bilge or perhaps even all of the inside of his hull! We await that information.

I wonder if they’d do a deal for a few gallons of the stuff.

Hadn't noticed it was the entire hull, rather than just the engine hole. 
I have never seen Vactan in  large containers but might be worth enquiring. 
I have seen Fertan in larger containers, but this needs rinsing according to literature.
Some people use Waxoyl but I find it stinks for months inside a boat. Even when I did the gas locker it was noticeable.
Some people swear by Owatrol oil, but not sure of the economics.
I was once told that old steel boats (Dutch barges?) were simply greased on the inside of the hull?

I've tried both Fertan and Vactan and Vactan is my choice every time. It seems to do the job better (lasts longer) and is easier to use with not having to wash it off. You can even apply it to damp surfaces.
